The circular statistics toolbox for Matlab

Directional data is ubiquitious in science and medicine. Due to its circular nature such data cannot be analyzed with commonly used statistical techniques. Despite the rapid development of specialized methods for directional statistics over the last thirty years, there is not a lot of software available that makes such methods easy to use for users. Most importantly, one of the most commonly used programming languages in biosciences, Matlab, is currently not supporting directional statistics. To remedy this situation, we have implemented a toolbox in Matlab, which covers diverse aspects of the statistical analysis of directional data.
